Slip on mirrors provide excellent towing visibility at an economical price, and are easily installed in minutes without any tools. The mirrors will not restrict the breakaway function of the OEM mirror housing nor the adjustment of the glass mirror.

How to Install the Longview Custom Towing Mirrors on a 2008 GMC Sierra

Today on this 2008 GMC Sierra we are going to install part number CTM1600. We have got the parts laid out in order of assembly we just have it enough for the one side of the truck. The part number does come with two sets of mirrors and hardware. We have got our mirror and we are going to set it face down for now so this is facing the front of the vehicle. We will take this part that has a hook that has a round flat part. We are going to put it through the top and it is going to sit inside like that. Then take this angle part and that will slide on just like this and then take the knob and thread it on about 1/ 2 inch of thread. Set it up just like that. 00:47

Because this part right here is an angle it will be going back towards the back of the truck. Then take this hook and start the knob on that just enough to get it started and at this point we can install the towing mirror on to the factory mirror of the truck. When you have everything together the mirror itself just slides on and follows the contour of the mirror. Once you have the mirror slid on to the factory mirror, take the parts and push them around and this hook will catch the end of the plastic and then just push it around and let it catch. Once you have it the way you want it tighten down the knobs. Also you can see where the parts contact the truck there are some felt strips that come with it to help protect it and with that, that is how you install the mirror and all you have to do now is set it up for your personal preference as you go down the road.
